Description

Wisteria is a fast-growing, long-lived woody vines with large, drooping racemes of fragrant flowers. Vines can grow 15 to 25 feet, so a large support structure is required to support them. An excellent vine for growing on trellises or arbors. Plants are hardy in zones 3 to 9.

How to Plant

Plant potted Wisteria Vine in spring after the danger of frost has passed. Prepare a planting hole 12 to 18 inches wide and deep and mix in compost or other organic matter. Plant with the roots slightly deeper than when growing in the pot. Wisteria can be somewhat slow to establish and begin flowering, and dislikes disturbance.

Maintenance

Needs full sun in moist, well-drained soil. Requires pruning twice each year for best flowering and to control growth. In summer after plants have flowered, prune side shoots back to about a foot long. In late winter, cut these shoots back to about 3 inches long, leaving 2 or 3 buds. Weak or overgrown shoots can also be pruned back in winter to shape plants. Overly heavy pruning can reduce or delay flowering. Fall root pruning can promote stronger flowering the next spring. To prune roots, use a shovel or spade to sever some roots about 12 to 18 inches from the main trunk in 2 to 3 spots. 

Fertilizer Recommendations

Wisteria is moderate feeder that benefits from annual fertilization. Use low rates of ALGOplus All Purpose 6-6-6 liquid fertilizer or Neptune Fish & Seaweed Fertilizer 2-3-1.

Common Problems

Usually not troubled with significant pest or disease problems. Japanese beetles and other leaf feeding insects occasionally occur. Overly shaded sites, pruning too heavily, and over fertilization can prevent or reduce flowering.

Alternative Products

Other perennial flowering vines include Clematis, Honeysuckle, and Maypop Passionflower.

Product Recommendations

Use Captain Jack's Deadbug Brew to control insect pests.
